Application filed January 31,1907. Serial No. 354.958.

1 To all whom it may concern:

of the United States, residingat Philadelphia, in the count of Philadelphia and State of Pennsylvania, ave invented certain new and usefulv 'Im rovements in Talking-Machines, of whic tion.

My invention relates to improvements in talking machines and the object of my invention is to provide a construction for pivotally connecting the sound-box and the soundconve ing-arm so that the weight of the latter wi l'not come on the record-disk, and the sound-box will be freeto rise and fall without lifting the weight of the sound-conveying the following is a specificaarm; a further object of my invention is to provide a core. having an annular spiral recess formed in its surface, which core is adapted to be inserted in thesound-conveying-arm to lengthen the distance of the assagewaythrou h which the sound trave s in coming from t e sound-box; a still further object of my invention is to construct a stand for supporting the parts ofthe talking machine so that the same may be readily attached to a phonograph havin a cylindrical record drum, thus utilizing t e means for driving the said drum to operate the recorddisk; a still further object of my invention is to im rove the manner of. mounting the recor -disk.

Referring to the drawings :--Figure 1 isa side elevation of a talking machine embodying my invention; Fig. 2: is a longitudinal sectional view through the sound-conveyingarm; Fi 3. is a side view of the core de-- tached ig. 4. is an end viewof Fig. 3; Fig. 5. is an end view of Fig. 2, showingfhe manner of mounting the sound-box; 'g. 6. is a side view of the record-disk-table, artly in section; Fi 7.. is 'a side view of t e lvotpost, detac ed, upon which the recor -d1sktable is mounted; Fig. 8. is a side view of the means used to secure the record-disk upon said pivotost.

In the rawings 1 represents the recorddisk-table and 2 the record-disk. The record-disk-table'is rotated by a friction rlng 3 mounted on the revolving cylinder or drum 4 of a honograph, having the usual mechanism or driving the said cyhnder located within the casing 6.

My improved means for mounting the rec ord-disk consists of the pivot-post 8 carried by an arm .9, connected to the vertical standrod 1( by an adjustable head 11 Be it known that I, DAVID KLINE, a citizen The standrod .10 has ,a reduced portion at its lower end to form a'shouldei', and the end of the standrod fits into an a erture formed in .the base 12 which is made eavy to support the Wei ht of the different parts of the device. he lower ortion 13 of the pivot-post 8 is screwthrea ed to receive a nut 14 which rests on the casing 6. By turning the said nut 14 the pivot-post 8 can be raised or lowered to Vary theamount of friction between thering 3 and the record-disk-table 1.

The record-disk-table has a sleeve 15,

which fitsover the pivot-post 8, and the said sleeve has slots formed in its upper end into which is locked the projections or pins 16 on the-shaft 17. The said shaft 17 has a conical recess 18 formed in its lower end which fits over the conical end of the pivot-post 8. The

shaft 17 and the pivot-post Bare of suflicient length when placed together to suspend the sleeve l5tcar the record-disk-table 1 so that the 'same wi rotate on the conical end of the pivot-post 8. The shaft 17 has a head 20 from which project arms 21 carrying weights 22 which act as a balance or governor to steady the movement of the reco'rd-disk table. The stand rod 10 carries an adjust able bearing 24 in which is mounted the usual form of elbow 25 and trumpet 26 used in talking machines. carries a sound-conveying-arm 27 pivotallv mounted between the set-screws 28 whic The elbow 25 su ort the outer end of the said arm.

e sound-box 30 has a tube 31 which is of smaller diameter than the end of the soundconveyin -arm 27 and is supported so that the end 0% the tube may enter the end of the said arm 27 without contacting with the latter. The said arm 27 carries a pin 32 over which fits a'sleeve 33 pivotally mounted in a core has a spiral groove 39 formed in its surface which orms a channel when the core is ti htly inserted-in the said arm 27 through w 'ch channel the sound must pass intraveling from the sound-box. Bymcreasing the length of travel ofthe sound the same is modified and the tone is greatly improved. A similar core may be inserted in the trumpet for a like purpose without departing:

from my invention.

By constructing the talking machine in the manner above described the parts may be readily assembled or taken apart and packed in'a small space. The operation of the different parts of the device is greatly simplified and the cost of construction reduced.

Having thus described my invention I claim and desire to secure by Letters Patent 1. In a talking machine, the combination of a sound-conveying-tube, a second soundconveying-tube of smaller diameteradapted to fit loosely into the first mentioned tube, a pin on said larger tube, a bearing on said smaller tube, and a sleeve mounted in said bearing adapted to fit over said pin and suspend the end of said smaller tube within the end of said larger tube.

2. In a talking machine, the combination of a sound-conveying-arm, a sound-box, a tube connected with said soundbox, a pin on said sound-conveying-arm, a sleeve adapted to fit over said pin, a bearing secured on said tube, and means for pivotally mounting said sleeve in said bearing.

3. In a talking machine, the combination of a sound-conveying-arm, a sound-box, a

tube connected with said sound-box, a pin on said sound-conveying-arm, a sleeve adapted to readily slip over said pin, a bearing secured on said tube, pivot points in said bearing to pivotally connect said sleeve and said bearing. 7

4. In a talking machine, the combination of a sound-box, a sound-conveying-member,

a core inserted in said sound-ponveyingmember, and said core havinga spiral groove formed in its surface to form a passageway for the sound.

5. In a talking machine, the combination of a record-disk-table, a sleeve secured in the latter, a pivot-post upon which said sleeve is loosely mounted, a shaft adapted to enter said sleeve and rest upon said pivot-post, and means for locking said sleeve and said shaft together; p

6. In a talking machine, the combination of a record-disk-table, a sleeve secured in the latter, a pivot-post upon which said sleeve is loosely mounted, a shaft adapted to enter said sleeve and rest upon the end of said pivot-post, a projection on said shaft, and

said sleeve having a slot formed therein toreceive the projection on said shaft and lock the said shaft and sleeve together.

7. In a talking machine, the combination of a record-disk-table, means for rotating the latter, a pivot-post on which said record-disk is mounted, arms mounted upon said disktable, and said arms having weights thereon.

8. In a talking machine, the combination of a record-disk-table, a pivot-post on which the latter is mounted, an arm carrying said pivot-post, a stand-rod, means for adjustably securing said arm upon said stand-rod, a sound-box, sound-conveying-members, and means for supporting said sound-box and said sound-conveying-members upon said adjustable bearing.

9. In a talking machine, the combination of a record-disk-table, a pivot-post on which the latter is mounted, an arm carrying said pivot-post, a stand-rod, a base, means for adjustably securing said arm upon said standrod, said pivot-post having a portion projecting below the said arm, a nut adjustably mounted on the latter a sound-box, soundconveying-members and means for supporting said sound-box and said sound-conveyin -members upon said stand-rod.

n testimony whereof I affix my signature in presence of two witnesses.
